  Developments in iron ore comminution and classifiion ...

   · Iron ore crushing and screening. Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel. About 98% of the mined iron ore is used to make steel either by the blast furnace—basic oxygen furnace (BFBOF) route—or through the electric arc furnace (EAF) route. The majority of world crude steel is made from the BFBOF .

  Bond Work Index

  Magdalinovic [38] measured the Bond work index of three ore types using different test screen sizes. He produced a correlation between the mass of test screen undersize per revolution, G, and the square root of the test screen size, D: () G = K 1 D. The constant K 1 is dependent on the ore type. Magdalinovic also produced a relationship between the test screen size and .

  Dry Processing

  The size classifiion by screening is one of the most important phases of production. During the wet processing, water is used to classify and purify the iron ore, removing impurities (such as silica) that affect the final product quality. Then, material must be exposed to moisture reduction processes in order to be stacked and transported to the clients. This processing route is used for ...

  types of ore screening

  These material screening devices prevent oversize muck from entering the ore pass. The most common types of these screens are grizzlies and scalpers, although scalpers tend to experience greater amounts of oversize blocks wedging between bars, resulting in higher maintenance costs. In the use of scalpers, it is common for operating crews to push the oversize through the scalper, this practice ...

  iron processing

  Crushing and screening are straightforward mechanical operations that do not alter an ore's composition, but some ores need to be upgraded before smelting. Concentration refers to the methods of producing ore fractions richer in iron and lower in silica than the original material. Most processes rely on density differences to separate light minerals from heavier ones, so the ore is crushed ...
